LV563505 | circuit breaker EasyPact CVS630F, 36 kA at 415 VAC, 630 A rating ETS 2.3 electronic trip unit, 3P 3d – Schneider Electric

Q: What load can the LV563505 protect at its rated 630 A?

A: The LV563505 is rated to carry and protect circuits up to 630 A continuously. For motor loads, ensure the full-load current (FLC) of the motor does not exceed this rating. For resistive loads (heaters, lighting), the 630 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: What does the 36 kA breaking capacity on the LV563505 mean in practice?

A: Breaking capacity (36 kA) is the maximum prospective short-circuit current the LV563505 can safely interrupt without damage. Before installing, verify that the prospective fault level at the installation point does not exceed 36 kA — this is checked using a fault level calculation or from the upstream transformer impedance data. Installing a breaker with insufficient breaking capacity is a serious safety violation.

Q: What trip unit type does the LV563505 use — thermal-magnetic or electronic?

A: Refer to the product label or datasheet for the exact trip unit specification. The trip unit determines adjustability and protection accuracy.

Q: Is the LV563505 suitable for use as a motor branch circuit protector (Type E coordination)?

A: MCCBs used for motor branch circuit protection must be coordinated with the downstream overload relay for Type 2 coordination (no damage to contactor or relay on short-circuit). Verify the Schneider Electric coordination table for the specific contactor-overload-MCCB combination to confirm Type 1 or Type 2 coordination is achieved.

Q: Can the LV563505 be motorised for remote switching and automation?

A: Yes. Schneider Electric MCCBs in this series support rotary handle adaptation and motorised operating mechanisms as accessories, enabling remote ON/OFF switching via PLC, SCADA, or BMS. Motorised MCCBs are used for automatic load management and remote trip in automated distribution systems.
